" ----- I say yes, The third is conclusive fact. I would use "Oswald killed Kennedy", but this MAY just still fall under a very strong theory. Nonetheless, it seems to me that the physical evidence all points to Oswald being there, and pulling the trigger -----"-

Common sense demands that Oswald was, as he himself declared, "A Patsy!".

First off, the cached rifle was not good enough to hit the target at that distance.
Secondly, Someone was shooting from the knoll, and what about the bullet on the stretcher?
Thirdly, Oswald was put away to close the case.
Fourthly and lastly, collusion was everywhere evident even where accredited investigators were employed. - I rest my case.
